Anti-trap protection method and device for an adjustable vehicle part

摘要

In the course of an easily implemented anti-trap protection method for an adjustable vehicle part, a test variable is continuously determined by way of a distance sensor during the adjustment of the vehicle part. A direct anti-trap protection test determines, based on the test variable, whether an obstacle is detectable in the adjustment path of the vehicle part. The adjustment is stopped or reversed if necessary. An indirect anti-trap protection test determines on the basis of the same test variable whether the movement of the vehicle part has slowed down irregularly or come to a stop, and the adjustment is stopped or reversed if necessary. An associated anti-trap protection device includes an anti-trap protection control unit, which is designed for automatically performing the method.

主权项

1. An anti-trap protection method for an adjustable vehicle part, the method comprising the following steps, to be performed continuously during an adjustment of the vehicle part:
acquiring a test value with the aid of a distance sensor; performing a direct anti-trap protection test based on the test value by ascertaining whether an obstacle is detectable in the adjustment path of the vehicle part and, if necessary, stopping or reversing the adjustment; and performing an indirect anti-trap protection test based on the same test value by ascertaining whether a motion of the vehicle part has slowed down in an irregular manner or has come to a standstill and, if necessary, stopping or reversing the adjustment.
